Same data/account on mobile, tablet, desktop, etc.

Tallies that more than one user can increment/de-increment.

Click the icon, tally is incremented. The app never even opens.

That is, anyone is freely licensed to use, copy, study, and change TallyLab in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. The only stipulation is that any derivative works are similarly licensed.

Bonus: Two-way continuous sync

A lot of people have been keeping personal data here for years already, plus it would be nice to sync recurring events, etc.

E.g. "you're getting close to missing your goal" or "you just met your goal"

Create and save various types of charts – pie, bar, line, etc. – and which data appears on the x and y axes

Automatically get geolocation for each count and add a map display to the tally and collection stats pages.

Randomly timed reminders to weigh in on a collection or tally. For example, random prompts to record your current mood.

E.g. automatically bring in data from Fitbit

Could be an aggregate of tally data, e.g. if it's a "Food" collection, and each tally has a numeric value for calories, the goal could be an aggregate of calorie count per day/week/etc.

Ability to save media with each count

Ability to setup a tally to have a goal of "30 minutes" per day rather than "1 count per day" etc.

Timers should count down from a certain duration and have an alarm sound when its done.

For example, maybe you want to run at least 20 miles a week and you don't care if you do that over one day or over several.

Set a numeric value that is automatically added at a certain interval of time, which can then be edited/delete later. E.g. for meds: Say you're pretty good at remembering to take them, but want to know later what broad range of time you were taking it, what the dosage was, etc.

Monthly report on what correlations exist in your data that you may not be aware of.

For example to track pain killer medication, most are every 4 hours but no more than 4 doses in a 24 hour period. Adding multiple goals where you aim to stay below both would help with the "at a glance" display

Would be lovely to have a way to get rid of tallies you no longer need to track but would like to keep the data already collected for.

Examples: For a food collection, you might want the default tally settings to include numerical values with the label "calories". For a fitness collection, you might want the default settings to include a goal of at least three times per week.

Would enable correlating any tally's data with whatever the current weather was in your location at the time

Ability to add units to the goal time interval, i.e. 3 days or 2 weeks

provide a compact view of tallies for mobile devices, allowing more to be visible at a given time. bonus: avoid clipping / having a tally partially visible as of 19 dec 2018, on an iphone x, in the all tallies view: scrolled to the top (default position) - two tallies are visible, the second is clipped (can’t reach stats or settings); scrolled down for maximum visibility - two tallies are visible and one is clipped (only half visible).

Sometimes it's nice to quickly type up a note and push it out. CLI clients are perfect for this.

Comes installed on iPhones

In the absence of push notifications from TallyLab itself, it would be nice to be able to use that functionality in the native alarms on most phones.

Instead of having to go to the tally after the fact, allow the user to have a note when adding the tally.

Ability to have multie values in a single tally. For instance, if tracking your Tetris 99 progress, you might track duration and place but it would also be interesting to know number of badges (do you place better with more badges?).

Automatically pull in tweets or FB posts, etc.

Show high-level stats on various tallies/collections to the world.
